    摘要: Electrochemical fabrication processes and apparatus for producing single layer or multi-layer structures where each layer includes the deposition of at least two materials and wherein the formation of at least some layers includes operations for reducing stress and/or curvature distortion when the structure is released from a sacrificial material which surrounded it during formation and possibly when released from a substrate on which it was formed. Six primary groups of embodiments are presented which are divide into eleven primary embodiments. Some embodiments attempt to remove stress to minimize distortion while others attempt to balance stress to minimize distortion.

    摘要: Some embodiments of the present invention are directed to techniques for building up single layer or multi-layer structures on dielectric or partially dielectric substrates. Certain embodiments deposit seed layer material directly onto substrate materials while other embodiments use an intervening adhesion layer material. Some embodiments use different seed layer materials and/or adhesion layer materials for sacrificial and structural conductive building materials. Some embodiments apply seed layer and/or adhesion layer materials in what are effectively selective manners while other embodiments apply the materials in blanket fashion. Some embodiments remove extraneous depositions (e.g. depositions to regions unintended to form part of a layer) via planarization operations while other embodiments remove the extraneous material via etching operations. Other embodiments are directed to the electrochemical fabrication of multilayer mesoscale or microscale structures which are formed using at least one conductive structural material, at least one conductive sacrificial material, and at least one dielectric material. In some embodiments the dielectric material is a UV-curable photopolymer.
